Abstract

A simple and rapid determination method for nitazoxanide (NTZ), an antiprotozoal agent, was developed using reverse-phase HPLC and Ultra Performance Liquid Chromatography (UPLC). Only six minutes gradient condition for NTZ analysis using UPLC was achieved. The mobile phase consisted of a mixture of phosphate buffer (pH 6.0) and acetonitrile. The repeatability (relative standard deviation (RSD), n = 6) and the correlation coefficient from linearity (the range from 80% to 120% of amount) were 0.25% and 0.9963 for UPLC and 0.15% and 0.9988 for HPLC, respectively. The quantitative values of NTZ in tablets were 103.2% for HPLC and 98.7% for UPLC. The RSDs of quantitative values of sample solution were calculated to be 4.06% to 4.64% for HPLC and 0.15% to 0.36% for UPLC.
